The extent of the burnt zone has been established by drilling. The thickest section, about 75 metres deep, underlies the Dry Lake gulch near the base of the coal measures. Other profiles of the bllrnt zone give an average thickness of about 25 metres, although thinning and some discontinuity is appartlnt. The present area of the burnt zone amounting to about 3.5 square kilometres is evidently o...

dwarf chicory (cichorium pumilum jacq.) is one of the annual species from chicory genus grows in western and southern parts of iran. to date no study on this species has been carried out under the field conditions. in order to determine the suitable planting date of dwarf chicory, an experiment was conducted in a split plot layout based on randomized complete block design with three replication...

pepino (solanum muricatum), a new vegetable crops, is from solanaceae family and cultivated as annual crops. in order to investigate the effects of mulch on weed dry weight in pepino and soil humidity and temperature, an experiment was conducted based on randomized completely design with three replication at the ferdowsi university of mashhad green house, during 2009. treatments included rice s...

[1] The phase boundary between San Carlos olivine and its high pressure phase, wadsleyite, have been studied comparatively in dry and water saturated condition. By comparing saturated and dry samples from the same experimental run, we determine that both boundaries of the two-phase coexisting loop shift towards lower pressure or lower iron content, and the pressure width of the loop decreases t...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...
